Hi Guy's I had a issue this weekend when a sensor on starboard side of 2002 5.0 gxi b(f) under the engine rotted off and started to pump water into the bilge when running and did not continue after it was shut down and bilge pump finally caught up. Alarm was going off. I can not locate this in my seloc book. I have to cut the nipple off that broke flush and could not be in a tougher spot. It has a single wire and a brass fitting with a 7/8 heater hose connected to it. I have the sensor out, I think it is a knock sensor and on the way back a short run the temp gauge did not work and the bilge pump had a tough time keeping up with the flow of water,Thankfully I did not have to go far when found.
